The 2.7 engine, or Chrysler LH engine, is a V-6 engine manufactured by Chrysler Corporation specifically designed for front-wheel drive vehicles. The engine is found in a wide variety of Chrysler vehicles including the Dodge Stratus, Chrysler Intrepid, Chrysler Sebring and the 2006 to 2010 Dodge Charger. The water pump in the 2.7 helps keep water and coolant flowing through the engine and coolant system. If it goes bad, it usually makes the car overheat. Bad water pumps should be replaced immediately.
